Coach Mark McCall has decided to go with Ryan Caldwell and Stephen Ferris ahead of Justin Harrison and Roger Wilson, respectively, in Ulster's Magners League joust with Leinster at Ravenhill this evening.
Scotland centre Rob Dewey will make his debut for the province in the centre beside Andrew Trimble and half-backs Isaac Boss and Paddy Wallace will be keen to prove a point to Ireland coach Eddie O'Sullivan.
Rory Best will lead Ulster in the continued absence of his brother Simon in a front row also containing Justin Fitzpatrick and Bryan Young.
Italian lock Carlo del Fava is still trying to find his feet in the middle of the pack.
